Tripleurospermum subnivale Pobed. (Asteraceae) is reported for the first time (A8 Rize) for the Flora of Turkey.
Trang 1The genus Tripleurospermum Sch Bip belongs to the
tribe Anthemideae of the family Asteraceae (Compositae)
and is composed of about 38 species distributed mainly in
Europe and temperate Asia, with a few species also in
North America and North Africa (Bremer & Humphries,
1993)
It is very similar to the genus Matricaria L in its
morphological characteristics and is also similar to many
other Anthemideae genera in its habitat Therefore, it has
been confused both taxonomically and nomenclaturally
with the genus Matricaria and other Anthemideae genera
(Jeffrey, 1979; Xifreda, 1985; Kerguélen et al., 1987)
The genus is represented by 26 taxa at the level of
species and variety in the Flora of Turkey (Y›ld›r›ml›,
1999) Most of these are distributed in north-east
Anatolia The first author collected some unrecognised
Tripleurospermum specimens during doctoral studies in
north-east Anatolia Some of them were later identified
as T subnivale Pobed using the account in the Flora of
the USSR (Pobedimova, 1995)
Materials and Methods
This study is based on herbarium specimens collected from north-east Anatolia in June 2001 Descriptions were written with the aid of the Flora of Turkey (Grierson, 1975), Flora Iranica (Podlech, 1986) and Flora of the USSR (Pobedimova, 1995) The morphological drawings were made with a drawing attachment Specimens were deposited at the Herbarium
at Karadeniz Technical University, Department of Biology (KTUB)

Discussion
In this paper, T subnivale is added as a new record for Turkey The total number of Tripleurospermum taxa
in Turkey is 27 at present
T subnivale is similar to T caucasicum (Willd.) Hayek but it differs in the following aspects: heads with a large involucre; involucral bracts with a broad black membranous margin, long and wide ligules, hemispheric receptacle, equal lobes of corona in achenes It also resembles T melanolepis (Boiss & Buhse) Pobed but it differs in its heads with a large involucre, long and wide bracts, ligules and achenes
